Technical Summary 

       Various published proposals for use of the IPv6 flow label are
       incompatible with its original specification in RFC 3697.
       Furthermore, very little practical use is made of the flow label,
       partly due to some uncertainties about the correct interpretation of
       the specification.  This document discusses and motivates changes to
       the specification in order to clarify it, and to introduce some
       additional flexibility.

RFC Editor Note

  Please change in Section 2:
  OLD:
  It is not made clear by the rule that there is an implied distinction
  between stateless models (in which case no assumption may be made)
  and stateful models (in which the router has explicit knowledge).
  NEW:
  It is   not made clear by the rule that there is an implied distinction
  between stateless models (in which there is no signaling, so no specific
  assumption about the meaning of the flow label value can be made)
  and stateful models (in which there is signaling and the router has explicit
  knowledge about the label).
